Headlamp Dimmer Switch: Testing and Inspection
RHEOSTATINSPECTION
1. Disconnect the negative (-) battery terminal.
2. Remove the crash pad side switch (A) by using the scraper (B) and then disconnect the connectors. Take care of fixing clips.
3. Check for intensity. If the light intensity of the lamps changes smoothly without any flickering when the rheostat is turned, it can be assumed that the rheostat is normal.
